[0029] The present invention will be further described below in conjunction with the accompanying drawings:

[0030] like Figure 1 — Figure 6 As shown, this embodiment provides a rotary tool setting and loading and unloading tool for an internal gear precision gear shaping workpiece, and the rotary tool setting and loading and unloading tool is adapted to the gear shaping tool 5 and cooperates to work. How to cooperate is detailed below. The rotary tool setting and loading and unloading tool comprises a rapid positioning system 1, a pressing system 2 and a rotating collection system 3. The pressing system 2 is installed on the rapid positioning system 1 through a threaded pair, and a clamping position is formed between the pressing system 2 and the rapid positioning system 1, thereby clamping the workpiece 4. The rotating collection system 3 is rotatably installed on the pressing system 2 to collect chips. The rotation axis of the rotating collection system 3 is located at the symmetric center line of the pressing system 2. The rotating collection system 3 comprises a rotating collection device 31 and a receiving bracket 32. The receiving bracket 32 ​​is rotatably installed on the pressing system 2 (the installed state is Figure 3 Please note that Figure 1 In order to simultaneously show the structure of the pressing system 2 and the relationship between the rotating collection system 3 and the workpiece 4, an exploded view is used. Figure 1The position of the middle and lower pressure system 2 becomes above the rotating collection system 3, but this state is only for demonstrating the structure, not the state during installation). The lower pressure system 2 serves as the rotation reference of the rotating collection device 31, ensuring that the rotation path of the rotating collection device 31 is always close to the to-be-processed surface 41 of the workpiece 4. A avoidance cone 311 is provided on the top of the rotating collection system 3, and the avoidance cone 311 is adapted to the gear inserting tool 5. The rotating collection device 31 follows the movement of the tool. A plurality of extrusion rotating components 312 are provided on the top of the avoidance cone 311, and the extrusion rotating components 312 provide power for the self-rotation of the rotating collection device 31. A plurality of attraction magnets 313 are provided around the rotating collection device 31 to absorb chips. A receiving hopper 33 is provided near the attraction magnet 313 of the receiving bracket 32 ​​to facilitate the collection of chips. Please note that the attraction magnet 313 has two functions, one is to attract iron chips, and the other is to make the rotating collection device 31 fit with the receiving hopper 33 during the rotation process, thereby ensuring that the rotating collection device 31 and the receiving hopper 33 rotate synchronously around the symmetric center line of the lower pressure system 2.

[0031] Specifically, the rapid positioning system 1 includes a bottom positioning plate 11 and a positioning gear 12. A positioning cone is provided at the bottom of the positioning gear 12. The bottom positioning plate 11 is adapted to the positioning cone, thereby ensuring that the axis position of the positioning gear 12 is accurate during installation. The positioning gear 12 is installed on the bottom positioning plate 11. The positioning gear 12 can be positioned by the internal gear segment that has been processed on the workpiece 4. That is to say, the workpiece 4 can be quickly positioned by clamping the processed internal gear contour on the outer contour of the positioning gear 12. The worker only needs to place the workpiece 4 on the positioning gear 12 to achieve the workpiece 4. Positioning, please note that in order to ensure the accuracy of the tooth position of the internal gear that has been processed on the workpiece 4 and the internal gear to be processed on the surface 41 to be processed, the traditional method requires the gear shaping tool 5 to be removed from the machine tool, and the gear shaping tool 5 to be rotated to adjust the position, and then the gear shaping tool 5 to be reinstalled after tool alignment, which is very troublesome. In this way, the tooth shape that has been processed on the workpiece 4 can automatically correspond accurately to the tooth shape position to be processed on the surface 41 to be processed, ensuring that the processing position of the surface 41 to be processed is accurate, there will be no misalignment, and it can work with the internal tooth shape that has been processed on the workpiece 4, preventing the workpiece 4 from being scrapped.

[0032] Specifically, a plurality of oil drain grooves 111 are provided on the bottom positioning plate 11 for discharging the coolant. However, please note that due to the blocking of the downward pressure system 2 and the positioning gear 12, and the relatively small hole originally opened on the workpiece 4 (the hole is provided by the workpiece 4 and is not part of this application), it is difficult for the coolant to carry out the iron chips.

[0033] Specifically, the pressing system 2 includes a pressing plate 21 and a pressing screw 22. The pressing screw 22 is installed on the rapid positioning system 1 through a threaded pair. A clamping position is formed between the pressing plate 21 and the rapid positioning system 1. The pressing screw 22 presses the pressing plate 21 to fix the workpiece 4.

[0034] Specifically, a mounting cylinder wall 314 is provided at the bottom of the rotating collection device 31 , and each attraction magnet 313 is mounted on the mounting cylinder wall 314 .

[0035] Specifically, a swivel pin 322 and an avoidance inclined arm 321 are provided at one end of the storage bracket 32. The swivel pin 322 can be rotatably installed on the rapid positioning system 1. The two ends of the avoidance inclined arm 321 are respectively installed with a receiving hopper 33 and a swivel pin 322. The top of the above-mentioned pressing screw 22 is provided with a swivel hole that cooperates with the swivel pin 322.

[0036] Specifically, the extrusion rotating assembly 312 includes a plurality of rotating spring pieces 3121, and a plurality of countersunk holes 31211 for installing the corresponding rotating spring pieces 3121 are provided on the rotating spring pieces 3121. Each rotating spring piece 3121 is installed obliquely on the avoidance cone 311. The inclination direction of each rotating spring piece 3121 points clockwise or counterclockwise. The ends of the rotating spring pieces 3121 are provided with rubber friction sheets 31212 installed by gluing. Since the gear inserting tool 5 is provided with a conical groove 51 adapted to the avoidance cone 311, when the gear inserting tool 5 is pressed down, the rotating spring piece 3121 is driven to be pressed down. 3121 gives a rotational torque to the rotating collection device 31, so that the rotating collection device 31 rotates, thereby driving each attraction magnet 313 to sequentially approach the receiving hopper 33 to collect chips. In order to further facilitate the rotation of the rotating collection device 31, the middle part of the bottom of the rotating collection device 31 protrudes for easy rotation. Please note that due to the need for feed, the workpiece 4 will slowly rotate under the drive of the machine tool, and the rotating collection device 31 will be gradually restricted by the gear shaping tool 5. The position of the rotating collection device 31 will be maintained on the lower side of the gear shaping tool 5, so that the rotating collection device 31 can be close to any position of the to-be-machined surface 41 of the workpiece 4.

[0037] Specifically, a material guiding slope 331 is provided at the bottom of the receiving hopper 33 and at one side of the receiving hopper 33 close to the rotating collection system 3 to facilitate the inflow of chips and the cleaning of chips.
